BOILER-FEED.

SPECIFICATION formngipart of v Letters Y'Patent No. 522,393, dated July3, 1.894.

Application filed September 1l 1893. Sverial No. 484,564. (No model.)

citizen of the UnitedStates, residing at Potts# town, in the county ofMontgomery, State of Pennsylvania, have invented a new and use` fulImprovement in Boiler-Feeds, which irnprovement is fully set forth inthe following specification and accompanying drawings. 1

My invention consists of novelv means forA heatlng the feed Water of asteam boiler or generator, and causing a circulation of the same throughthe boiler and heating device, as will be hereinafter set forth.

Figure I represents a side elevation of a boller feed embodying myinvention. Fig. 2 represents a top or plan view thereof. Fig. 3represents a longitudinal section of one ,of the valves thereof; Fig. 4represents a section on line Fig. 3.

Similar letters of reference indicate correspondmgparts in the severalfigures.

Referring to the drawings:,A designates a boller feed of any desiredconstruction and B designates the water supply or feed pipe thereof.Connected with said pipe Bis a pipe C, which extends under the'jboiler,and hasv connected with it thereturn pipe or bend D, which is Within thevfurnace E, and'is connected with one end of the drum F, the latterformlng the bridge Wall of the furnace. Connected with the other end ofthe drum is a plpe G, which is also `locatedwithin the furnace, similarto the return pipe D, it being lllustrated below the broken-away part inFlg. 2, and connected with the pipe H, which extends under the boilerand is connected with the branch J,which leads into the boiler as at K.

At the junction of thepipes B and C is an automatically-operating valveL, the same consisting of a shell M having within the same the head orvalve N, and seats P and Q at opposite ends, so that said valve L may beclosed on the seat P, and opened on the seat Q, or vice-versa, it beingnoticed that the pipes B and C are coupled to the shell M, andcommunicate with the interior thereof. Leading from the shell of thevalve L, and openb ing into the boiler is a branch pipe B.

' The Walls of the seats P and Q are formed with grooves R, whichconstitute channelsY which permit the passage of Wateror steam,

as the case may be, around said valve N.

The pipe B is provided with a valve S for regulating the iow of water tothe 'feed pipeB- r "l The operation is as follows: The valve S isopened, and waterl flows into the pipelB,'and pressing against the valveN closes the same against the seat P, whereby ysaid valve is open onthe'seat Q.- The water now'l'lows through the valve and enters the pipe C,it being noticed that steam is cutoff from the pipe C,

owing to the closed valve N, as shown in Fig.

3. The water then ows through the pipe C land the pipe D, and crossesthrough the drum F into the pipe G, and flows through the pipes H, J,and so enters the boiler in highly heated condition, as the pipes D andG, certain portions of the pipes C and H, and the drum F are subjectedto the direct products of combnstion in the furnace E, and the remainderof the pipes C and H are subjected to the products of combustion underthe boiler behind said drum, the latterV acting asy the bridge Wall ofthe furnace, the effect of which is evident. When the boiler issupplied, the valve S is elosefd,`and the iiow of Water ceases, and thevalve L having the water pressure removed therefrom is now subjected topressure from the boiler through the pipe B'. This causesthe valve N toopen on the seat P, and close on the seat Q, whereby the pipe C is incommunication with the boiler through the pipe B', and the Water may nowcirculate through the boiler and theseveral heating pipes, thuseffectively producing steam in large volumes.

Having thus described my inventiomwhat I claim as new,l and desire tosecure by Letters Patent, is y 1. A boiler feed consisting of a feedpipe, a heating pipe leading from said feed pipe to a boiler, a steampipe and a shell connecting said feed, heating and steam pipes, andhaving 'an automatic valve adapted to either open or close thecommunication between the feed and heating pipes, and closeor open thecommunication between the steam and heating pipes, said parts beingcombined substantially as described.

2. A boiler feed having a feed pipe, a heating pipe in communicationtherewith and leading into a boiler, a steam pipe communieating withsaid heating pipe and an automatic valve controlling the communicationsbetween said feed, heating and steam pipes, said parts being combinedsubstantially as described.

3. In a boiler feed, the shell M having seats at its Opposite ends withchannels in their walls, the pipes B and B connected with the ends ofsaid shell, the pipe C connected with said shell intermediate Of saidpipes B and B', and the valve head N in said shell adapted toautomatically open or close the communication betweon pipes B and C, orB and C, Substantially as described.

4. A boiler feed and heater therefor con sisting of the feed pipe B, theheating pipes C, D, the communicating heating pipes G and II, theheating drum and bridge wall F connecting said pipes D and G, and anautomati cally-acting valve intermediate of the pipes B and C, adaptedto open said feed pipe and then close the same, causing a circulation ofwater through the boiler and heating pipes, said parts being combinedsubstantially as described.

5. A boiler feed and heater therefor, consisting of a feed pipe with thevalve S therein, a heating pipe in communication with said feed pipe, adrum forming the bridge wall of a furnace, a pipe leading from said druminto the boiler, a shell with valve seats in each end, and a valve headin said shell, aseetion of said feed pipe being between said shell andboiler, and said valve-head controlling the communication betweensection of feed pipe and the heating pipe, said parts being combinedsubstantially as described.

6. A boiler feed having a feed pipe, aheating pipe, and a shell with anautomatic valve therein, a section of said feed pipe being intermediateof said shell and boiler, and said valve controlling the communicationbetween said section and the heating pipe, and also the communicationbetween the main body of the feed pipe and the heating pipe, said partsbeing combined substantially as described.
